Effect of acupuncture at " three points of ilioumbar" on lumbar function and pain in patients with iliopsoas muscle strain / 中国针灸

OBJECTIVE@#To compare the clinical effect of acupuncture at "three points of iliolumbar" combined with celecoxib and celecoxib alone in the treatment of iliopsoas muscle strain.@*METHODS@#A total of 60 patients with iliopsoas muscle strain were randomly divided into an observation group and a control group, 30 patients in each group. Celecoxib was given orally to both groups, 200 mg once a day for 3 days. On the basis of the above drugs, acupuncture was applied at (Extra), Wushu (GB 27), (Extra) in the observation group, once a day for 3 days. The Japanese Orthopaedic Association (JOA) score and visual analogue scale (VAS) score were observed and compared before and after treatment, and the content of 5-hydroxytryptamine (5-HT) in serum was detected by enzyme-linked immunosorbent assay (ELISA) before and after treatment in the two groups.@*RESULTS@#After treatment, the JOA scores in the two groups were increased (both <0.05), and the VAS scores and 5-HT contents were decreased (all <0.05). The increase of JOA score in the observation group was greater than that in the control group (<0.05), and the decrease of VAS score and 5-HT content in the observation group was greater than that in the control group (both <0.05).@*CONCLUSION@#Acupuncture at "three points of ilioumbar" combined with celecoxib in the treatment of iliopsoas muscle strain can improve lumbar function, relieve pain and reduce 5-HT content in serum, which is better than celecoxib alone.

Inhibition of EV71 replication in vitro by polysaccharides from Selaginella tamaritcina / 国际药学研究杂志

Objective To evaluate the inhibitory effect of polysaccharides from Selaginella tamariscina on Enterovirus 71 (EV71) replication in vitro. Methods For detecting the cytotoxicity, series of doses of polysaccharides from Selaginella tamariscina were added in RD cells, cell survival rates were evaluated by observing the cytopathic effect (CPE) and using cell counting Kit-8 (CCK8) assay, then the half toxic concentration(CC50) of the drugs were calculated. For studying the antiviral activity, the cellular model was established by infecting RD cells with EV71. Several groups were set in the experiments: normal control group, virus-infected group, positive drug treated EV71 -infected group(ribavirin 3. 2 mg/L) and series of doses of polysaccharides treated EV71 -infected groups. The CPE inhibitions were determined by using CCK8 assay and the half inhibitory concentrations of drugs(IC50) were calculated. The inhibitiory effect of polysaccharides on EV71 RNA were determined by using real-time RT-PCR methods for detecting the virus RNA levels in cell cultures. Results The CC50 of 30% and 50% alcohol precipitated polysaccharides from Selaginella tamariscina on RD cells were 396 and 142 mg/L, respectively; the IC50 calculated according to the CPE inhibitory rates were respectively 40. 8 and 26. 2 mg/L. Additionally, these two polysaccharides significantly reduced viral RNA copies in EV71-infected RD cells. Conclusion Selaginella tamariscina together with its 30% and 50% alcohol precipitated polysaccharides can be developed as potential new anti - E V 71 drugs.
